The MLS series has been developed with technology taken from the hugely successful MLI Ultra series. Although tailored for different types of applications, the MLS share many of the same characteristics making them ideal for applications where long lifespan, light weight and compactness are key.
Lithium Ion has many advantages over lead-acid, meaning the MLS series can fast recharge in an hour, and deep cycle (up to 80 % discharge) 2.000 times without damage, which is three times longer than traditional lead-acid. Also for MLS the safest Lithium Ion chemistry available (LiFePO4) is used.
The MLS has an integrated battery management system including a safety disconnect which protects the battery from deep discharging, overcharging and overheating. The products make an ideal energy storage solution, and create an optimal entry point into the world of Lithium Ion.
The MLS series is designed to be extremely easy to install without any additional components. All the models comprise of a tough waterproof plastic case. This makes it a straight-forward replacement for most existing lead-acid batteries.
The new MLS batteries are suited for many different applications where capacity up to 90 Ah is needed. Its compactness and low weight plus the fact that it is mountable in multiple orientations, make it ideal for portable applications such as mobile communications. The MLS is also often used for (UPS) backup power. Applications range from small boats and vehicles to security systems and industrial applications.
